The expansion coefficients \(a_6, \bar{d}_5, q_{44}, q_{63}\)  and \(q_{82}\)  emerge at 5PN.
In [1]} the following values were obtainedThe reader should not be
confused with the values given in [2]}, which are in the f–scheme of the authors.
We compare to the h–scheme, cf. [1]}.
\({\rm 5PN}, u^2~: &~q_{82} \hspace*{-42.67912pt} &=&~\frac{6}{7} \nu + \frac{18}{7} \nu ^2 +\frac{24}{7} \nu ^3 - 6 \nu ^4,\\u^3~: &~q_{63} \hspace*{-42.67912pt} &=&~\frac{123}{10} \nu - \frac{69}{5} \nu ^2+ 116 \nu ^3 - 14 \nu ^4,\\u^4~: &~q_{44} &=&~\left(\frac{1580641}{3150} -\frac{93031}{1536} \pi ^2\right) \nu + \left(-\frac{9367}{15} + \frac{31633}{512} \pi ^2 \right) \nu ^2+ \left(640 - \frac{615}{32} \pi ^2\right) \nu ^3,\\u^5: &~\bar{d}_5 &=&~\left(\frac{331054}{175} -\frac{63707}{512} \pi ^2 \right) \nu + \bar{d}_5^{\nu ^2} \nu ^2+ \left(\frac{1069}{3} - \frac{205}{16} \pi ^2\right) \nu ^3,\\u^6: &~a_6 &=&~\left(-\frac{1026301}{1575}+ \frac{246367}{3072} \pi ^2\right) \nu + a_6^{\nu ^2} \nu ^2 + 4 \nu ^3.\)
